Evidence of a role for the 5-HTTLPR genotype in the modulation of motor response to antidepressant treatment.

Rationale: Serotonergic mechanisms are thought to play an important role in the regulation of mood, motor activity and sleep patterns. Serotonin reuptake is controlled by the serotonin transporter (5-HTT) and by a common functional insertion/deletion polymorphism in the corresponding gene's promoter region (5-HTTLPR). Homozygosity for the long variant may confer a favourable response to treatment with serotonin reuptake inhibitors (SSRIs), and to sleep deprivation.

[No association of 141C-ins/del polymorphism in the D2 dopamine receptor gene in schizophrenia].

Recently, a putative functional polymorphism (-141C Ins/Del) in the 5'-flanking region of the dopamine D2 receptor was found. An association of the Ins allele with schizophrenia has been described in a Japanese sample. In the present study this association was examined in a German schizophrenia patient population.

[No Association of the - 141C Ins/Del Polymorphism of the Dopamine D2 Receptor with Schizophrenia].

Recently, a putative functional polymorphism (- 141C Ins/Del) in the 5'-flanking region of the dopamine D (2) receptor was found. An association of the Ins allele with schizophrenia has been described in a Japanese sample. In the present study this association was examined in a German schizophrenia patient population.

The auxin-induced maize gene ZmSAUR2 encodes a short-lived nuclear protein expressed in elongating tissues.

By differential screening of a cDNA library from auxin-induced maize coleoptiles we have isolated and characterized a SAUR gene, designated ZmSAUR2, belonging to a not yet characterized subtype of the SAUR family. ZmSAUR2 encodes a 15.3-kDa protein and is specifically induced by auxin in elongating coleoptile tissue but not in primary leaves or in roots.

Association of dopamine D3-receptor gene variants with neuroleptic induced akathisia in schizophrenic patients: a generalization of Steen's study on DRD3 and tardive dyskinesia.

Neuroleptic induced akathisia is a common and distressful extrapyramidal side effect of antipsychotic treatment. A significant proportion of the variability of its development has been left unexplained and has to be attributed to individual susceptibility. Since hereditary factors have been discussed in the etiology of acute akathisia (AA), part of the individual susceptibility might be of genetic origin.
